[ http://issues.apache.org/jira/browse/MYFACES-222?page=comments#action_64271 ] Mike Kienenberger commented on MYFACES-222: -------------------------------------------
Thanks, Mathias. I'll make sure I'm using the final version of 1.0.9 (it's unclear which version of 1.0.9 I have, so it probably isn't the final version). Sorry for the duplicate bug report, but I did a jira search for UIColumns before posting to the mailing list and opening a bug. Unfortunately, [MYFACES-174] didn't include "UIColumns" in any searchable form. One concern I have about the described fix in [MYFACES-174] is that all of the changes took place in UIData rather than UIColumns. Seems like UIColumns needs to be more robust, particularly if it is intended to be usable in other JSF implementations. On the other hand, that's currently an unimportant issue. > UIColumns loses rowIndex on renderColumnBody > -------------------------------------------- > > Key: MYFACES-222 > URL: http://issues.apache.org/jira/browse/MYFACES-222 > Project: MyFaces > Type: Bug > Versions: 1.0.9 beta > Environment: myfaces-1.0.9 > Reporter: Mike Kienenberger > Assignee: sean schofield > > I'm using UIColumns (myfaces-1.0.9), and I've hit what appears to be a bug. > I can initialize my page, and then update my page, but I get an > IllegalArgumentException("row is unavailable") exception when the page > is being rendered (but after all of the actions for that page have > been processed). > The problem appears to be in here: > HtmlTableRendererBase.encodeChildren() contains: > columns.setRowIndex(k); > String columnStyle = styles.getColumnStyle(j); > renderColumnBody(facesContext, writer, > uiData, child, columnStyle); > k starts out as 0. renderColumnBody() eventually calls > UIColumns(UIData).isAllChildrenAndFacetsValid() line: 646 > UIColumns(UIData).encodeBegin(FacesContext) line: 594 > RendererUtils.renderChild(FacesContext, UIComponent) line: 482 > HtmlTableRenderer(HtmlTableRendererBase).renderColumnBody(FacesContext, > ResponseWriter, UIData, UIComponent, String) line: 205 > and isAllChildrenAndFacetsValid cycles through the rowIndexes, and > ends up setting it to -1. > And then sometime later my own code gets called via > HtmlSelectBooleanCheckbox(UIOutput).getValue() line: 75 > RendererUtils.getBooleanValue(UIComponent) line: 213 > HtmlCheckboxRenderer(HtmlCheckboxRendererBase).encodeEnd(FacesContext, > UIComponent) line: 94 > HtmlSelectBooleanCheckbox(UIComponentBase).encodeEnd(FacesContext) > line: 341 > RendererUtils.renderChild(FacesContext, UIComponent) line: 491 > RendererUtils.renderChildren(FacesContext, UIComponent) line: 468 > RendererUtils.renderChild(FacesContext, UIComponent) line: 489 > HtmlTableRenderer(HtmlTableRendererBase).renderColumnBody(FacesContext, > ResponseWriter, UIData, UIComponent, String) line: 205 > but by this point, the rowIndex is -1 rather than the original 0 value > it should have been. > I "fixed" this in a 2005-04-29 CVS checkout with the following patch. > However, I don't claim to know if this will break something else. > Index: UIColumns.java > =================================================================== > RCS file: > /home/cvspublic/incubator-myfaces/src/share/org/apache/myfaces/component/UIColumns.java,v > retrieving revision 1.1 > diff -u -r1.1 UIColumns.java > --- UIColumns.java 29 Mar 2005 11:40:50 -0000 1.1 > +++ UIColumns.java 29 Apr 2005 22:27:45 -0000 > @@ -15,7 +15,10 @@ > */ > package org.apache.myfaces.component; > > +import java.io.IOException; > import javax.faces.component.UIData; > +import javax.faces.context.FacesContext; > > /** > * @author Mathias Broekelmann (latest modification by $Author: matzew $) > @@ -53,4 +56,18 @@ > { > return COMPONENT_FAMILY; > } > + > + public void encodeBegin(FacesContext context) throws IOException > + { > + int savedRowIndex = getRowIndex(); > + super.encodeBegin(context); > + setRowIndex(savedRowIndex); > + } > + > + public void encodeEnd(FacesContext context) throws IOException > + { > + int savedRowIndex = getRowIndex(); > + super.encodeEnd(context); > + setRowIndex(savedRowIndex); > + } > } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
